CORNER-STRIP FOR BUILDINGS.

SPECIFICATION formingpart of Letters Patent No. 593,150, dated November2, 1897.

Application filed November 20, 1896. -Seriel No. 612,896. (No model.)

1'0 aZZ whom it may concern;

Be it known that I, FRANKLIN Woons, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Corner-Strips for Buildin gs, of which the following isa specification.

The object of my invention is to manufacture a cheap and substantialcorner-strip adapted to besecured to the two adjoining walls of abuilding and to project from the the corner, so as to protect theplaster, as fully described hereinafter.

In the accompanying drawings, Figure lis a perspective view illustratinga corner of a wall, showing my improved corner-strip in position, theupper portion of the figure showing the plaster. Fig. 2 is a transversesectional view of the walls, showing the cornerstrip in position. Fig. 3is a side view showing the openings for the plaster. Fig. 4: is a planview of the blank, showing a method of cutting. Fig. 5 is a view of thecut strip separated. Fig. 6 is a side view of one of the cut strips bentto the proper angle. Fig. 7 is a sectional view on the line 7 '7, Fig.6. Fig. 8 is a View looking in the direction of the arrow, Fig. 5. Figs.9 and 10 are views of modifications of the invention.

Referring in the first instance to Figs. 4:-

and 5, which illustrate the preferred method of making the strips, A isa strip of sheet metal, preferably galvanized iron. This strip I cut intwo longitudinal sections on the scroll line a: by suitable mechanism,so as to produce two sections B B. (Shown in Fig. 5.) These sectionseach have projections or wings b b, which are bent to the proper angle,so that the strip can be adapted to a projecting corner. The projectionsor wings b of one section when out out form spaces 0 in the othersection, so that there is no waste, as the metal of the entire strip isutilized; but I may increase the space between the wings when a lightcorner-strip is required.

The wings I) of each strip alternate with the wings I), one set beingpreferably bent in one direction and the other set being bent in theopposite direction, as shown in Figs. 6, 7, and 8. If, for instance, thecorner is a rightangled corner, then the wings are bent at an angle offorty-five degrees to a liney drawn through the projecting rib a of thestrip, as shown in Fig. 7, so that the rib, when the corner-strip isapplied to the partition or other wall, will project at the corner, asshown in Fig. l so that the plasterer can work up to the strip at eachside.

It will be noticed that the wings are separated by the spaces 0. Thesespaces are formed in the present instance by the cutting out of theprojections or wings of the adjoining strip, where two strips are madefrom one sheet, as describedabove and as shown in Figs. 4: and 5.

The wings or projections are preferably bent on a line a, Fig. 6, whichis some distance from the inner edge of the rib a and is in the presentinstance at the narrowest point or neck of the wing. By bending thewings at this point Iform a series of openings when the strip is appliedto the wall, as in Figs. 1 and 8, through which the plaster extends, sothat the plaster at the strip will be interlocked therewith, as clearlyshown in Figs. 1, 2, and 3. This prevents the cracking and spreading ofthe plaster at the point where it joins the strip.

I preferably puncture the projections or wings I) h for the reception ofthe securingnails, although when the strip is made of light material thewings may be punctured by the nails or by the lather when the strip isplaced in position; but I prefer to make the strip of comparativelythick material, so that it will not buckle out of shape when beingapplied, as it is important that the rib a of the strip should beperfectly straight.

The finished strip can be readily shipped, as one strip will interlockwith another in packing, so that a quantity of the material can bepacked in a small compass and in such a manner that the strips will notbe distorted in handling.

I preferably use galvanized iron, so that the projecting edge will notmark or otherwise disfigure the plaster or paper if the room is paperedafter plastering.

\Vhile I prefer the form shown in Fig. l, the cutting may be angular, asshown in Fig. 9, or the strips may be cut as shown in Fig. 10.

Iclaim as my invention- 1. As a new article of manufacture acorner-strip having a rib a, wings I), 17 projecting therefrom atintervals, the wings I) bent at an angle to the rib a, and the wings 1)alternating With the Wingsb and bent at an opposite angle to the wingsI), said Wings being bent at a point some distance from the rib so as toform interlocking spaces for the plaster in the projecting portion ofthe corner-strip, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

FRANKLIN O ODS.
